Just 90 companies worldwide produced fuels that generated two-thirds of industrial greenhouse gas emissions from 1854 to 2010, according to a new study.

The 90 biggest producers of fuels driving climate change include investor-owned corporations, such as Exxon Mobil and Chevron, and state-owned oil companies, such as Saudi Aramco and Mexico’s Pemex.

The study attributes 914 billion metric tons of greenhouse gases to the fuels extracted by the companies, which is 63% of the total 1,450 billion metric tons of emissions estimated since the mid-19th century.
